Following Ms Patel's interview on Sunday morning, he said herd immunity had not been a "secret" policy but an "official strategy" explained on TV and radio.

He said herd immunity had been viewed as "unavoidable" until 9 March when government policy started to shift to "Plan B" - to "dodge herd immunity until vaccines [were available]".

He continued to tweet on the subject throughout Sunday and ahead of his appearance on Wednesday before the Commons Health and Science Select Committee which is considering lessons to be learned from the pandemic.

Mr Cummings was the prime minister's closest political aide, and in the room when decisions were being made early in the pandemic.

But, since parting ways with his boss last November, he has become a trenchant critic of Mr Johnson's actions.

Early on in the pandemic, the government's chief scientific adviser's comments about herd immunity attracted attention.

On 13 March 2020, Sir Patrick Vallance told BBC Radio 4's Today programme, the government's aim was to "try and reduce the peak - not suppress it completely, also because most people get a mild illness, to build up some degree of herd immunity whilst protecting the most vulnerable".

Sir Patrick later insisted that herd immunity was "not the plan" and the Department of Health said his comments had been misinterpreted adding: "Herd immunity is not part of our action plan but is a natural by-product of an epidemic."

There are two ways of achieving herd immunity: First is through the natural progression of the disease, which will cause illness and death as people become infected. The second is through vaccination.

The right to health, as with other rights, includes both freedoms and entitlements:

Freedoms include the right to control one’s health and body (for example, sexual and reproductive rights) and to be free from interference (for example, free from torture and non-consensual medical treatment and experimentation).

Entitlements include the right to a system of health protection that gives everyone an equal opportunity to enjoy the highest attainable level of health.
